A Survey of Different DC Faults in a Solar Power System

The growth of the renewable energy industry has become faster than ever before and it now plays an essential part in the studies and applications of solar power systems. The maximum power of a solar power system will decrease in abnormal conditions; therefore, it is necessary to monitor, identify, and detect the different faults on the DC side of the solar system. There are several factors which are considered significant keys to increasing the reliability, lifespan and efficiency of the solar power system; however, some of these are classified as physical faults that will pose damage on the solar power system while others are identified as electrical faults on the DC side of the system. Through this paper, a survey on the most type of faults on the DC side of a solar power system will be presented with a summary of some detection methods proposed in recent literature.
